Specification of Letters Patent.

Patented Apr. 3, 1911.

Application filed August 31, 1916. Serial No. 117,923.

To all whom it may concern I Be it known that I, FRANK A. UHLs, a citizen of the United States, residing at Cheraw, in the county of Otero and State of Colorado, have invented certain new and useful Improvements in Hay-Stackers of which the following is a specification.

This invention relates to an improved hay stacker and the principal object of the invention is to provide a hay stacker in the form of a vehicle having an improved supporting means for the vehiclebody so that the vehicle body may be vertically lifted and held in a raised position, thus permitting the hay or grain contained in the body to be easily transferred to the stack.

Another object of the'invention is toso construct the, supporting means for the wagon body that the body may be either partially or entirely raised according to the height of the stack.

Another object of the invention is to so construct this support that the standards for holding the super-structure in an elevated position, may be slidably mounted and guided in their sliding movement when the Wagon body. is raised or lowered.

Another object of the invention is to provide improved means for moving the standards longitudinally of the wagon and to further provide improved brake means for controlling the speed at which the standards will move to permit the dropping of the wagon body.

This invention is illustrated in the accompanying drawings, wherein Figure 1 is a view in side elevation of the improved vehicle.

Fig. 2 is a front elevation of the improved vehicle;

Fig. 3 is a view similar to Fig. 1 showing the wagon body partially raised instead of entirely raised.

Fig. 4 is a top plan view of the improved vehicle with the wagon body or box removed.

Fig. 5 is an enlarged fragmentary sectional View showing the construction and operation of the brake mechanism.

Fig. 6 is an enlarged detail view showing the manner of connecting certain of the rods forming part of the frame.

Fig. 7 is an enlarged fragmentary View of the frame construction.

Fig. 8 is an enlarged View showing the manner of slidably mounting one of the standards.

This stacker is provided with a carriage or vehicle body 10 which is supported by the forward and rear Wheels 11 and 12 mounted upon the axles 13 and 14. The rear supporting wheels carry sprocket wheels 15 which turn with the wheels and it will thus be seen that the rear wheels will constitute driving wheels for transmitting rotary movement to the shaft 16 through the medium of the sprocket chains 17 passing around sprocket wheels 15 and around sprocket wheels 18 mounted upon the shaft 16.

The receptacle 19 is connected with a sup porting frame 20 by means of hinge cleats 21 and latches 21, the end bars of which carry pivotally mounted elevating standards 22 and 23, the lower ends of which carry yokes 24 which are pivotally connected with carriages 25. These carriages 25 are slidably mounted upon tracks carried by the frame 26 of the wagon body 10 and from an inspection of the drawing and particularly Fig. 7, it will be readily seen that each track is provided with an'upper rail 27 and a lower rail 28, the rails being connected with the end plates 29; These upper and lower rails are connected with the end plates by means of bolts 30, the upper ones of which engage bolts 31 which serve to connect the tracks with the frame 26 carried by V the wagon body. It will be seen that the tracks will be very securely held in place and that as the carriages 25 are provided with rollers 32, they may move easily along the tracks. Drums 33 are mounted upon the shaft 16 and carry lines 34 which extend about pulleys 35 and are connected with the yokes 24. It will thus be seen that when the sprocket wheels 18 are moved so that their clutches 36 are brought into engage mentwith the clutches 37 carried by the shaft 16 and the shaft rotated to wind the lines 34 upon the drums 33, the standards 22 and 23 will be moved toward the position shown in Fig. 1, thus raising the receptacle 19. This receptacle 19 is provided with guides 38 which engage the rods39 slidably mounted in the posts 40 and therefore the receptacle will be guided in its vertical movement and prevented from swinging forwardly or rearwardly during raising and lowering of the receptacle. I u

Latch levers 41 and 42 are mounted upon opposite sides of the drivers seat 43 where they may be reached easily, each being connected with a draw rod shown in Fig. 4 and designated by the numerals 44 and 45. The draw rod 44 is connected with the brake lever 46 which brake lever is pivotally mounted by means of the brackets 47 and is connected with the brake band 48 extending about the brake drum 49 and secured to the crossbar 50. By means of this brake the rotation of the shaft can be controlled and thus the receptacle lowered after the hay has been removed therefrom without danger of it moving downwardly too rapidly.- The draw bar 45 is connected with the bell-crank lever 51 which is pivotally mounted upon the cross bar 52 and has its end portions connected with the links 53 extending beyond the sides of the frame or wagon body and connected with the shifting levers 54 which levers are pivotally mounted upon the brackets 47 and 55 and engage the clutches 36 so that when the latch lever 41 is moved, the clutches may be moved into and out of engagement with the clutches 37.

When in use, the clutches 36 will be moved out of engagement with the clutches 3'7 and the machine can then be driven across the field and loaded, the receptacle being at that time in the lowered position. When .the receptacle is filled, the vehicle will be driven toward the points where the stack is to be built and unloaded. As the stack increases in height-,it will be necessary to raise the vehicle and in order to do so, the lever 41 will be moved to bring the clutches into engag'ement' and the shaft 16 will then be rotated and the lines or cables 34 wound upon the drums 33 thus moving the standards 22 and 23 to raise the receptacle. After the receptacle has been emptied, the clutches canbe released and the receptacle then permitted to return to the lowered position by its own weight, the brakes being of course applied in order to prevent the receptacle from descending too rapidly. The latches 21 are provided so that when desired these latches may be released and the receptacle 19 swung'upon the hinge cleats 21 for dumping. One side 19 of the receptacle is hinged to permit of its being dropped when cleaning the receptacle or removing hay there from. 7 a
